Contribution of Benthic Processes to the Growth of Ooids on a Low-Energy Shore in Cat Island, The Bahamas [PDF]

open access: yes, 2018
Ooids are typically found in frequently reworked coastal sediments, and are thought to accrete by inorganic chemical precipitation around moving grains. The high organic content and the presence of biosignatures, however, suggest that ooids interact with

Boussinesq Modelling of Shallow Water Phenomena

open access: yesEnvironmental Sciences Proceedings, 2022
The phenomenon of wave breaking dominates the hydrodynamics of the surf zone. Therefore, numerical modelling of shallow water phenomena requires a proper reproduction of the wave breaking mechanism.

Occurrence and abundance of young mullet Mugil liza (Teleostei: Mugilidae) in the surf zone along the southern coast of Brazil

open access: yesScientia Marina, 2021
The southern population of Mugil liza is distributed from Argentina (47°S) to the state of São Paulo, Brazil (23°S). Young mullets use the estuaries as nursery grounds, and prior to recruitment into estuaries they use the surf zone as a temporary habitat.

Influence of Beach Slope on Morphological Changes and Sediment Transport under Irregular Waves

open access: yesJournal of Marine Science and Engineering, 2023
This paper presents new data from large-scale wave flume experiments. It shows the beach profile evolution and sediment transport for two different bed slopes (1:15 and 1:25), and three irregular high-energy erosive wave conditions and one low-energy ...

Beach cusps and inner surf zone processes: growth or destruction? A case study of Trafalgar Beach (Cádiz, Spain)

open access: yesScientia Marina, 2010
Large beach cusps (LBC, wavelength of ~ 30 m) are intertidal features that can alternately exist in the swash and in the inner surf zone due to tidal sea level changes. They have a larger cross-shore extent (up to 50 m) than traditional cusps.

Nearshore oblique sand bars [PDF]

open access: yes, 2003
The coupling between hydrodynamics and the evolving topography in the surf zone has been theoretically examined for oblique wave incidence. It is shown that positive feedback can lead to the initial growth of several types of rhythmic systems of sand ...

Oil Transport in Surf Zone [PDF]

open access: yesJournal of Hydraulic Engineering, 2000
Oil transport subjected to nearshore currents in the surf zone is considered using the mass conservation equation. Analytical solutions are obtained that describe the longshore distribution of oil deposition, as well as the length of the shoreline contaminated by oil slicks transported in the nearshore environment.

Bathymetric Inversion and Uncertainty Estimation from Synthetic Surf-Zone Imagery with Machine Learning

open access: yesRemote Sensing, 2020
Resolving surf-zone bathymetry from high-resolution imagery typically involves measuring wave speeds and performing a physics-based inversion process using linear wave theory, or data assimilation techniques which combine multiple remotely sensed ...

Surf-zone vortices over stepped topography [PDF]

open access: yes, 2004
The problem of vortical motions in the surf zone is simplified by taking the bottom topography to be piecewise flat while allowing finite-height jumps in depth between flat regions.

Bed level changes in the surf zone during post-storm beach recovery

open access: yesFrontiers in Marine Science, 2023
The study of post-storm beach recovery is important for economic development and the protection of life in coastal areas. In this study, field observations were conducted for 21 days in the surf zone of Dongdao Beach, Hailing Island, China, after ...
